Referring to the drawings for a more detailed description, 1() indicates a china or ceramic fitting, conventionally illustrated as -a spout, having a bore 11 enlarged at its rear end to form a chamber 12. The bore ot' the spout at the chamber 12 tapers from a` shoulder 13 toward the rear end of the spout. That is to say, the Wall 14 of the chamber converges toward the rear opening 15. The chamber, as thus formed, constitutes a seat for a flexible gasket 16 of material which is soft or yielding as compared to metal, and may be, for instance, rubber. 'lhe gasket may be inserted into the chamber 12 through the rear opening 15 by flexing the same, and when it enters the chamber, it will expand as illustrated in Figure 2, and closely fit in the spout. The periphery of the gasket is preferably inclined to correspond to the inclination of the chamber Wall 1li, and since the gasket is formed for the close fit illustrated, it will be held against free rotation, due to the frictional engagement between its periphery and the wall 14. Furthermore, it will be held against free longitudinal movement not only by the frictional engagement, but also by abutment of one face 'with the sl'ioljxlder 13.

After insertion of the gasket into its seat, a metallic sleeve 1T threaded internally to lit upon the supply pipe S extending through the Wall lV, may be inserted into the chamber, and into the central opening 1G of the gasket. lt maybe explained that the Wall W is simply illustrative of any fixed element, such as a portion of a tub, basin, or even a wall or partition of a building against which it is not unusual to position a supply spout in the more modern installations.

Referring to the metallic sleeve 17, the same has a bevelled forward end 18 which facilitates insertion of the sleeve into the gasket, and it is of a suilicient size to lit closely Within the opening 1G of the gasket. On its periphery, the sleeve has tWo spaced flanges 19, 20; the former is at the forward end of the sleeve, and may be provided, if desired, with means such as eorrugations 20', adapted to positively interlock with the gasket, and thereby assist the relatively tight lit of the gasket bore with the sleeve in preventing rotation of the sleeve within the gasket.

'l`he sleeve and gasket as thus positioned within the spout (Figure 8) constitute a coinplete assembly to be mounted upon the supply pipe S. The sleeve is connected With the spout through the gasket because of the frictional engagement of the sleeve With the gasket, and the positive engagement of the eorrugations 20', if used. Independent rotation of the sleeve Will not occur, and the tight fit of the gasket in its seat Will prevent rotation of the gasket in the spout. Consequently, by positioning the spout upon the supply pipe S, and rotating it, the sleeve will be threaded upon the supply pipe, and continned rotation of the spout, after its rear end engages the wall 1V, will cause the sleeve to continue its travel along the supply pipe, thereby pressing the gasket toward the rear end of the spout. Due to the tapering bore of the spout around the gasket, the latter Will be compressed as it is forced rearwardly in the spout by the flange 19 of the rotating sleeve to clamp the spout against the Wall and the final position of the parts is substantially as illustrated in Figure 1. It will be observed that there is effected a sufficient conu'n'ession of the gasket to insure a watertight seal at its periphery, and this compression being transmited inwardly, also affords a water-tight seal around the sleeve at the central opening in the gasket.

ifhen the parts of the connection are finally tightened. it may be found desirable to give a partial revolution to the spout to properly direct it With reference to the tub or basin with which it is set up, and this may be accomplished Without releasing the joint or danger' of breaking thespout simply by ap'- plying sufficient 4force to overcome the trictionalengagement between the gasket and spout, and around the' latter.

somewhat niodii'iedconstruction in that the spout at its rear end is 'counter-sunk, as at 21, to providea seat'for `alsecond and bevelled gasket 22 which is linterposed betiveen thev rear ot the spout and ythewvall WV., This gasket closely surroundsthesiipply pipe S,

vand being gripped between the 'wall'V andthe `there 'is Lillustrated another modifie ation which corresponds to that shown Y in'Figure/i in all respects, except that seat 23 is provided for a gasket `2st, theVWalls of the gasketand seat being atjsubstantially right angles to one-anotherinstead of iiid clined as inFigure ,4.7

, and the end'lange 31.

In the forni of Figure '5, in Whicliza sleeve 25, similar'to the sleeve 17j-of -F-i'gursl isY employed, and is vprovided additionally upon its rear -tlange 26, with means, such as the rib 27, tointerlock with asecond gasket 28 interposed between the flange and the Wall YV. This gasket, asillustrated in Figure 6, not extended upwardly into ,a seat formed in the spout'y as in'Figures 4 and, although,

obviously, this variation would not be a departure troni tlieinvention. ,The gasket 28 closely surroundsthek supply pipe S, and

when compressed by the'i'lange 26 ot thev sleeve 25, assists the gasket 16 in'preventi-ng leakage. g t i Figures 9 to 14 inclusive, shoiv'moditied forms of ,connection sleeves which may be substituted for the sleeves illustrated in Figures 1 to 6;

Referring to Figure 9, the sleeve E29 lacksv means upon the `flange 30 for positivev engagenient iviththe gasket^,but such means as the corrugations 32, is provided upon the 'portion of thesleeve between the flange 30,'

Y In the form of the invention illustra-ted in Figures ll'and 12, the sleeve B3 has means for positively engaging the gasket upon the inner 'face' of flange 34,' such-means being the ribs or corrugations Similar corrugations 36 are provided upon the portion oi the sleeve which tits within the gasket.

In Figures 13 and 1st, there is illustrated l; terring to Figure 4,Jthere is shown aV engaged `and. gasket correspond to similar parts another Vform lof sleevein -Which the portion of the sleeve l37= Which fits Within the gasket 38 is-formedwitha; plurality of longitudinally extending keys-or ribs 39, which fit closelyin suitablei'key-vvays i() which are pre- V:termed inthe gasket `38, land-insurerotation 1 ofthe sleeve `with the gasket when the-latter Vislrotated hy the spout.

Re i'erring to `Figure l15, a. ceramic or china spout of slightlydiil'erent torni from that 'illustrated irl-Figure 1 is shown as tixedly attached, by means of the connection described, to a threaded nipple 42, Which may be in turn threaded intoa supply pipe The sleeveil illustiated -in 'Figure i1, and a metal plate' or flange 46 is rotatably mounted upon the shank for adjustment thereon. rilhis plate lserves as `ali-abutment for the spout in tightening the connection.V 'second gasket i7 surrounds the plate '4G and projects rearwardly lfrom the vspout a` greater-distance than'v the platein orderfto abut the Wall ot any iixtureto whichtlie spout maybe applied.` It Wi-ll be `observed that both ,the t plate 46V andgasket 47 are arranged in a seatV i8 counter-sunk'in the rear end-of the spo-ut, f ;V I i In Figui'ev16 there is shown a. slight modification ofthe sleeve 17"/ illustrated'in Fig'- ure L1. As will be observed',\the periphery 49 of the sleeve 50 :is tapered for a substantial distance and preferably froinlthe end oi the sleevef'tof'the flange 51, ThisV `construction facilitates the insertion :of the sleeve into the rubber gasket 16 (Figure 4).

The connection describedv is particularly useul withl ceramic `spouts, and other tittings oi" Afran'giblecharacter, since there is no direct contact betiveenjthevmetal connections and theceraniic'material. hloreover, it unnecessary tolformthe spout `With threading, key-Ways, or other connecting means et anyv .character foi" engagement with the metallic parts, and thus the constructionv ol the spout onuse'vvith this connectionis not dillicult. 1 fV v A It will be understood, of course, that the invention is not limited to the precise structural details illustrated and described, and

where suoli terms as spout, gasket and' sleeve are-employed, 4to designate conventionally constructed parts, `they are to be interpreted as covering any equivalent means accomplishing the ldesired result. For instance, the invention is useful `with any ceramic Water supply iitting, such sprayY heads, vfaucets, and the like. u y
